Why have gas stations removed the gas pump gizmo which allows you to NOT hold the pump while filling up?
The auto-fill device was removed because of the frequency of the auto shut off to fail sometimes. The rationalization is that if there is someone holding the nozzle and the fuel begins to overflow, that it can be stopped more easily.
It also was done as a time saver. If you have to stand there while filling, you are more apt to get the task done quicker - when other are waiting in line to fuel, this helps everyone get to the pumps quicker and back on the road. Nothing is more aggrivating than someone who has started filling the tank, then goes into the mini-mart to do their weekly grocery shopping for 20 minutes or so.
